# exit(2)

## NAME

         exit, _exit - terminate a process

## SYNOPSIS

         void _exit(int status)

## DESCRIPTION

         _exit terminates a process with the following consequences:

              All of the descriptors open in the calling process are closed.  This
              may  entail  delays,  for  example,  waiting  for output to drain; a
              process in this state may not be killed, as it is already dying.

              If the parent process of the calling process is executing a wait  or
              is interested in the SIGCHLD signal (Minix-vmd), then it is notified
              of the calling process's termination and the low-order eight bits of
              status are made available to it; see wait(2).

              The parent process ID of all of the calling process's existing child
              processes  are  also  set  to 1.  This means that the initialization
              process (see intro(2)) inherits each of these processes as well.

         Most C programs call the library routine exit(3), which performs  cleanup
         actions in the standard I/O library before calling _exit.

## RETURN VALUE

         This call never returns.
